Bleeding stress and metabolic changes in the crab Scylla tranquebarica (Fabricius)

In the crab scylla tranquebarica, bleeding stress is characterized by changes in proteins, lactic acid and water content of muscles, hepatopancreas and haemolymph. Proteins seemed to be involved in energy expenditure and internal osmotic balance. Lactate levels increased, suggesting a shift in aerobic metabolism. Water content fell.
